Particle moving in a delta potential

A particle of mass m, with energy E>0, is moving in the potential
V(x)=g[delta(x+a) + delta(x-a)]

Assuming that the particle is incident from the left, what is the solution of the Schrodinger equation in all three regions (x<a, -a<x<a, x>a) for this situation? Also, what are the appropriate continuity conditions at x=+a and x= -a?
